摘要： 欧盟自2011 年1 月份新增RCAR（汽车修理研究协会）保险杠低速碰撞的测试评估。为了解
新增RCAR 测试将如何影响保险等级的评估，本文根据RCAR 保险杠低速碰撞试验及评价方法，以及
低速碰撞车辆的设计思路和方法，用Oasys 和Hypwork 等模拟软件，对某SUV 实车进行了仿真分析。
结果为：该实车防撞梁本体的刚度差，且防撞梁和保险杠之间没有支撑物，因此不足以提供碰撞过
程中的支撑力; 该实车防撞梁的中心线高度与壁障可变形部分的中心线高度没有在同一条直线上，故
车体损坏件较多，降低了该车的保险等级。提出了一些改善汽车被动安全的措施。

Abstract: Bumper low-speed structural crash tests proposed by Research Council for Automobile Repairs
(RCAR) were added to the official insurance level assessment programs by European Commission in January
2011. Bumper low-speed crash was simulated for a real sports utility vehicle (SUV) to analyze the effects of
the new RCAR tests on the insurance rating evaluation adopting Oasys and Hypwork software tools, the test
and evaluation methods of RCAR, and the design concept for vehicles in low speed crash. The results show
low stiffness of the bumper beam with the absence of underpins between the bumper and the bumper beam
resulting in poor support in the crash. Barrier’s deformable section center line does not align with the bumper
beam center line, which induces heavy damage and reduces the vehicle insurance rating. Some measures are
given to perfect vehicle passive security.
